Re: Bypassing internal amp (and maybe pre-amp) in a DVD Rece
I've learned a little more info.
I called Onkyo technical support and asked them what Q4001 does and whether it handles pre-amplification or not. They told me Q4001 "does the switching and volume control". That's what the engineer...
Re: Bypassing internal amp (and maybe pre-amp) in a DVD Rece
I puzzled over SD-1 some more (SD-1 referring to the schematic for the pre-amp part of U01 board).
I came to the conclusion that my reading of the diagram was probably too simplistic. I am pondering about the actual purpose of...
Re: Bypassing internal amp (and maybe pre-amp) in a DVD Rece
Here is the board schematic for the Pre-amp section of U01 (the board that houses Pre-amp and DSP).
Split images show the board a little bit better.
My understanding is that the IC chip in the center (Q4001) is the main switch for...
Re: Bypassing internal amp (and maybe pre-amp) in a DVD Rece
Ah, so that's why low-capacitance cables are advised for interconnects.
Am I using this resistor for when I want to bypass both the pre-amp and the amp? (I assume that the signal from the internal pre-amp doesn't need this if I'm...
The main jist of my post is this: I would like to attempt bypassing a power amp and maybe even the pre-amps in my receiver to get to the purer signals right after the DSP (digital sound processor). The central question for what follows is this: can I tap or split a signal in the circuit board...
